OTSU Gray-level image segmentation using Otsu s method. Iseg = OTSU(I,n) computes a segmented image (Iseg) containing n classes by means of Otsu s n-thresholding method (Otsu N, A Threshold Selection Method from Gray-Level Histograms, IEEE Trans. Syst. Man Cybern. 9:62-66 1979). Thresholds are computed to maximize a separability criterion of the resultant classes in gray levels. OTSU(I) is equivalent to OTSU(I,2). By default, n=2 and the corresponding Iseg is therefore a binary image. The pixel values for Iseg are [0 1] if n=2, [0 0.5 1] if n=3, [0 0.333 0.666 1] if n=4, ... [Iseg,sep] = OTSU(I,n) returns the value (sep) of the separability criterion within the range [0 1]. Zero is obtained only with images having less than n gray level, whereas one (optimal value) is obtained only with n-valued images.

Java has become a confusing world. Five years ago, there were few decisions to make once you started programming in Java—you used AWT for graphical user interfaces, sockets for network programming, and hacked together everything else you needed. Since then, though, the APIs available for the Java language have grown, and grown. . . and grown. Now you can dabble in Swing, servlets, Enterprise JavaBeans (EJB), JavaMail, and more. Additionally, there are now packages of APIs, like the Java 2 Micro Edition (J2ME) and Java 2 Enterprise Edition (J2EE). While these packages seem to be nicely wrapped bundles of useful APIs, they don t help the average developer figure out how to piece together the APIs contained in these packages. Though it s simple to find documentation on the individual APIs, getting the "big picture" is difficult, at best. One of the most interesting, but difficult, aspects of Java today is building Java enterprise applications using the J2EE package.

program which uses hashing techniques for storing and retrieving the data. Input to the program: Some random numbers. Input will be from a file. Output: First the program reads all the input and store it properly using some hash techniques. Once your program reads the complete input,it waits for the user input (prompt to the user). User now enters some number.program displays if this number exists in the list or not. it also display the time taken in the search operation.

As a programming language, C is rather like Pascal or Fortran.. Values are stored in variables. Programs are structured by defining and calling functions. Program flow is controlled using loops, if statements and function calls. Input and output can be directed to the terminal or to files. Related data can be stored together in arrays or structures.

This is a desktop application written in java which sends email using gmail smtp. You do not need to go to the browser to send email. If you do not have a gmail account that is ok too because you can send email by a default account and of course by your own account. You need jdk 1.6 or higher to run it.

Traveling Salesperson Problem Our branch-and-strategy splits a branch and bound solution into two groups: one group including a particular arc and the other excluding this arc. 1.Each splitting incurs a lower bound and we shall traverse the searching tree with the "lower" lower bound. 2.If a constant subtracted from any row or any column of the cost matrix, an optimal solution does not change.
